    “In addition, we are not persuaded by Patent Owner’s argument that Stine1998 is not “salient to the Relevant Problems disclosed in the ’946 patent” because Stine1998 “relates to oxide CMP in a subtractive process,” which, according to Patent Owner, is directed to different problems, and different CMP than the metal CMP in a damascene process. PO Resp. 35. As Petitioner points out, Jaso, Stine1998, and the ’946 patent each address the “erosion of dielectric and dishing of metal” during CMP, which gives rise to “a non-planar surface.” Pet. 6 (citing Ex. 1001, 3:25–44, Fig. 4), 30– 31 (citing Ex. 1004, 2:7–19), 36–37 (citing Ex. 1004, 3:29–64; Ex. 1005, 668). Patent Owner’s assertion that different issues cause dishing and erosion too narrowly confines the problem that the references address. See Unwired Planet v. Google, 841 F.3d 995, 1001 (Fed. Cir. 2016) (“The field of endeavor of a patent is not limited to the specific point of novelty, the narrowest possible conception of the field, or the particular focus within a given field.”). Patent Owner also asserts “Jaso’s reference to ‘dishing’ is categorically different from the problems with which the ’946 patent is concerned: dishing of wide interconnect and erosion of oxide between dense narrow interconnect.” PO Resp. 63. We are not persuaded by this conclusory statement.10 Furthermore, to the extent Patent Owner argues the references are non-analogous art, all the references are directed to the creation of metal lines in chip manufacturing, as discussed above, and fall within the same field of endeavor.” slip op. at 31

    “Petitioner argues it would have been obvious to a person of ordinary skill in the art to combine Jaso and Stine1998 “to etch a plurality of dummy trenches in a dielectric layer between a first (wider) trench and a series of second (narrower) trenches.” Id. at 66 (citation omitted). Petitioner argues that a person of ordinary still in the art “would be motivated to combine the teachings in Jaso and Stine1998, as both references are directed to the addition of dummy conductors to equalize pattern density to improve CMP planarity.” Id. at 38–39 (citing Ex. 1004, code (57), 3:29–64; Ex. 1005, 668). In particular, Petitioner states that “Stine1998 enhances and improves upon the disclosure in Jaso by providing general teachings and specific methods that are widely applicable to dummy metal-fill techniques for addressing added capacitance.” Id. at 39 (citing Ex. 1005, 670–672). Petitioner points out that “Stine1998 expressly motivates a [person of ordinary skill in the art] to apply its teachings to a damascene process requiring dummy-fill to enhance planarity” because Stine1998 states its methodology can be extended to “inlaid metal techniques such as copper (emphasis omitted). Analysis of Patent Owner’s Arguments 1) Prior Art Does not “Look for” a Specific Configuration Patent Owner argues “Stine1998 does not tell the POSA to look for a specific configuration of structures, and then insert dummy metal into a particular location within that configuration (as the Relevant Solution does.)” PO Resp. 36–37. Patent Owner also argues that Jaso and Stine1998 “together accordingly tell the POSA to focus on pattern density, and to take steps to ensure that variations in pattern density across the chip are minimized” as opposed to looking for the particular configuration called out by the claims. Id. at 58. There is no requirement in the claims for the prior art to “look for” specific structures, but rather it must disclose those structure required by the claims. For the reasons articulated in the Petition, we agree that the combined teachings of Jaso and Stine1998 teach the structure required by claim 1.

We also credit Dr. Boning’s testimony that these references’ teachings “to locate dummies in sparse regions proximate to wide and narrow lines...would obviously include placing dummies in regions between such lines.” Ex. 1002 ¶ 183 (emphasis added). The fact that Jaso and Stine1998 may not purposefully seek out the configuration relied on by Patent Owner does not undermine Petitioner’s showing that the proper configuration would result from an obvious combination of the references.

    “look at Figure 8 and form any understanding of its structures at all” and thus, Dr. Boning’s opinions should be disregarded in their entirety. Id. at 44 (citing Ex. 2011 ¶¶ 191–199). We find that the explanations by Dr. Boning are a reasonable attempt to explain what one of ordinary skill in the art, with general background knowledge in the art, would glean from Figure 8 of Stine 1998 and are supported by additional cited references, such as Maly1991 and the StineThesis. See, e.g., Ex. 1052 ¶¶ 72 (citing Maly Fig. 4), 92 (citing Ex. 2016 (StineThesis), 92 (Ex. 2016, 165), 93. “[A] skilled artisan’s background knowledge is relevant to the reading of the prior art on which the obviousness challenge is based and . . . it is permissible, and sometimes even necessary, to establish such background knowledge by pointing to other prior art.” Rovalma, S.A. v. Bohler-Edelstahl GmbH & Co. KG, 856 F.3d 1019, 1027 (Fed. Cir. 2017). Despite Patent Owner’s criticism, Dr. Boning’s testimony cited by Patent Owner evidences Dr. Boning’s opinion that a person of ordinary skill in the art was aware of common artifacts and limitations in downscaled Boning also relies on secondary references to support his testimony about the general background knowledge of one of ordinary skill in the art. Ex. 1002 ¶¶ 65 (citing Ex. 1009 (Mead Textbook)), 74 (citing Ex. 1010 (Rabaey Textbook)), 75, 76, 152–157. Thus, we credit Dr. Boning’s testimony and do not disregard his testimony wholesale based on those alleged inconsistencies. Below, we focus on the testimony that is at issue in this IPR. There are three main reasons why Figure 8 of Stine1998 is at issue. First, Petitioner asserts that the white areas in Figure 8 are open areas between a wide trench and narrow trenches with no metal lines into which dummy conductors would be placed. See Pet. 37–38; Ex. 1002 ¶¶ 112, 152, 157. Patent Owner opposes that contention (PO Resp. 56) but, as explained in association with claim construction, we do not rely on a construction that requires no intervening trenches or other structures between the wide trench and narrow trenches. Additionally, Petitioner relies on the typical layout of chips and the figures of Jaso to support its interpretation of Figure 8. Pet. 45–46, 52–53. 13 Dr. Givens testifies that, because there is a discrepancy in Dr. Boning’s testimony regarding the inserts for various regions of Figure 8 of Stine1998 and the lack of any other inserts one of ordinary skill in the art would not assume the white areas contain no metal lines. Ex. 2011 ¶¶ 195–196. And, based on his magnification experiment, Dr. Givens testifies that Figure 4 of Maly1991 may contain metal lines. Id. We consider the fact that Dr. Givens’s testimony is largely based on what a person of ordinary skill in the art could discern from Figure 8 of Stine1998 and Figure 4 of Maly1991 alone rather than what one or ordinary skill in the art may glean based on their background knowledge in the art—for example whether Figure 8 of Stine1998 is consistent with conventional chip designs as Dr. Boning testified. Thus, we give slightly more weight to Dr. Boning’s testimony.” slip op. at 35

We also credit Dr. Boning’s testimony that these references’ teachings “to locate dummies in sparse regions proximate to wide and narrow lines...would obviously include placing dummies in regions between such lines.” Ex. 1002 ¶ 183 (emphasis added). The fact that Jaso and Stine1998 may not purposefully seek out the configuration relied on by Patent Owner does not undermine Petitioner’s showing that the proper configuration would result from an obvious combination of the references. Thus, we are not persuaded by these arguments. Dummy Trenches We also disagree with Patent Owner’s argument that “Stine1998 does not teach or suggest any ‘trenches in a dielectric layer.’” PO Resp. 47, 55– 56. Patent Owner argues that Stine1998’s “subtractive process used for the manufacture of the disclosed chip does not involve the formation of such trenches.” Id. at 47 (citing Ex. 2011 ¶ 171). That is, Patent Owner asserts Stine1998 deposits a dielectric layer around already-formed metal lines. This argument, however, is not commensurate with the scope of the claims as properly construed. As noted above, to the extent that a damascene process is required, Jaso teaches such a process. Pet. 44. Additionally, assuming arguendo Patent Owner’s argument is correct, it stands to reason that the spaces where dielectric is not deposited are free of dielectric (due to the presence of metal lines) and, therefore, the “trenches” are free of dielectric. Patent Owner also asserts Stine1998 does not disclose dummy trenches because it “states in passing that certain areas of its test chip would be ‘prime candidates’ for ‘metal-fill,’ but does not actually disclose the particular location of any alleged ‘dummy’ conductor.” PO Resp. 56 (citation omitted) (citing Ex. 2011 ¶ 205). Patent Owner’s argument improperly attacks Stine1998 alone when Petitioner argues that the combination of Jaso and Stine1998 teaches “trenches.” See In re Keller, 642 F.2d 413, 426 (CCPA 1981). Petitioner points out that Jaso describes “a damascene method wherein, in general, a via or trench pattern is etched into a planar dielectric layer.” Pet. 44 (emphasis omitted) (citing Ex. 1004, 1:28– 31; 8:5–8; Ex. 1002 ¶¶ 142–144). Petitioner states that Figure 11B of Jaso includes “trenches (15a-d) [which] correspond to trenches for interconnects 45. Patent Owner does not address the trenches taught by Jaso, much less teachings of Jaso in combination with the teachings of Stine1998. See PO Resp. 33–36, 55–61. Accordingly, we are not persuaded that the combination of Jaso and Stine1998 fails to teach “trenches.”” slip op. at 29

  • Skill levelSkill level petitioner adoptedDecided for petitioner

    “Petitioner asserts a person of ordinary skill in the art of the subject matter of the ’378 patent would have had “(a) a bachelor’s degree in computer science or electrical engineering, and four or more years of experience with networks and networking devices, or (b) a master’s degree in computer science or electrical engineering, and two or more years of experience with networks and networking devices.” Pet. 10 (citing Ex. 1105 ¶¶ 30–34). Patent Owner does not offer a proposed level of skill in its Patent Owner Response and does not address Petitioner’s assertions regarding the education or experience of an ordinarily skilled artisan at the time of the invention. See generally PO Resp. We adopt Petitioner’s articulation of the level of skill and acknowledge that the level of ordinary skill in the art is also reflected by the prior art of record. See Okajima, 261 F.3d at 1355; GPAC Inc., 57 F.3d at 1579 (Fed. Cir. 1995); Oelrich, 579 F.2d at 91.” slip op. at 8

  • Claim Construction › Intrinsic evidence (Phillips canons) › Plain and ordinary meaning to a POSITATerm construed patent owner constructionDecided for patent owner

    “All challenged claims require a “hardware queue.” Petitioner argues “under BRI, the term ‘hardware queue’ should be interpreted to include hardware that is configurable by software to form a queue.” Pet. 42 (citing Ex. 1105 ¶ 210). Petitioner also suggests that an alternative definition of the term could “require special-purpose hardware circuitry to control at least some portion of the queue.” Id. at 44. Patent Owner does not define explicitly “hardware queue.” Nevertheless, Patent Owner’s declarant asserts “[t]he plain and ordinary meaning of a hardware queue, is well known,” i.e., that “such a queue would be designed by a circuit designer and formed to function as a queue as part of the manufacturing process of an electronic circuit,” and that it differs from a software queue “formed by software operating on general purpose or multi-purpose hardware.” Ex. 2001 ¶ 34. Additionally, Patent Owner’s argument in the Patent Owner Response suggests “hardware queue” means that the queue cannot be a “software queue” and “must be implemented in hardware.” PO Resp. 7, 9–12 (stating “Petitioners do not assert that the queue must be implemented in hardware”).” slip op. at 9

  • Obviousness (§103) › Motivation to combine / reasonable expectation of successMotivation foundDecided for petitioner

    “Petitioner demonstrates reasons supported by a rational underpinning for combining Wilford and Ayres, including at least that the combination uses known methods to obtain predictable results. Pet. 61–66. For example, Petitioner provides evidence and argument that: A [person of ordinary skill in the art at the time of the invention] would have understood that monitoring CPU utilization as taught in Ayres is a conventional technique for monitoring CPU load in relation to the CPU’s capacity, and that known technology could be employed in Wilford to monitor utilization of the linecard’s CPU (as Ayres does) and provide that information to the added dynamic packet flow rate control module. (Lavian, ¶259 (discussing Ayres and citing Ex. 1112 at 4:67, 9:62-65, 10:18- 20, and 10:26)). Pet. 66.

  • Strike new argumentNew argument consideredDenied

    “because it contains allegedly new arguments. Paper 24. Specifically, Petitioner states Patent Owner argued for the first time “a hardware queue” requires some unspecified “structure” “define[d]” by hardware “such as shift registers.” Paper 42, 2 (citing Sur-Reply at 2–3). Petitioner also asserts that Patent Owner, for the first time in “[t]he Sur-Reply[,] offers unsupported attorney arguments about alleged differences between the ‘hardware queues’ in Exs. 1110 and 1111 and Wilford’s queues based on alleged differences between SRAM and DRAM.” Paper 42, 3 (citing Sur-Reply at 2–3). Petitioner asserts Patent Owner’s arguments could have been made in the Patent Owner Response and thus are waived. Paper 8, 3 (arguments not in POR “will be deemed waived”); Update to the Trial Practice Guide (83 Fed. Reg. 38,989 (Aug. 13, 2018) (notifying the public of the updated “Trial Practice Guide” and its accessibility through the USPTO website: https://go.usa.gov/xU7GP)) at 15 (a “sur-reply that raises a new issue or belatedly presents evidence may not be considered”; a sur-reply may “respond” to arguments “raised” in the reply but “respond … does not mean embark in a new direction with a new approach as compared to positions taken in a prior filing.”). Petitioner’s motion is denied. Patent Owner’s reference to “shift registers” is in response to arguments in the Reply regarding the definition of hardware queue. Additionally, Patent Owner’s reference to Exhibits 1110 and 1111 are in response to Petitioner’s reference to those exhibits for the first time in its Reply.” slip op. at 37

    “written description. To satisfy the written description requirement of 35 U.S.C. § 112 ¶ 1, the specification must “clearly allow persons of ordinary skill in the art to recognize that the inventor invented what is claimed.” Ariad Pharm., Inc. v. Eli Lilly & Co., 598 F.3d 1336, 1351 (Fed. Cir. 2010) (internal brackets omitted) (en banc) (quoting Vas–Cath Inc. v. Mahurkar, 935 F.2d 1555, 1563 (Fed. Cir. 1991)). Thus, the specification must reasonably convey to those skilled in the art that the inventor possessed, at the time of filing, the subject matter that he or she has claimed. Id. “[T]he level of detail required to satisfy the written description requirement varies depending on the nature and scope of the claims and on the complexity and predictability of the relevant technology.” Id.

  • Claim Construction › Intrinsic evidence (Phillips canons) › Plain and ordinary meaning to a POSITATerm construed board ownDecided for patent owner

    “We determine that because the open ended term “comprising” was used in the original claim reciting “a” signal, the recitation of “a” signal and “one or more” signals would have the same scope. An indefinite article, such as “a,” in patent parlance encompasses “one or more” when used, as here, in open-ended claims containing the transitional phrase “comprising.” KCJ Corp. v. Kinetic Concepts, Inc., 223 F.3d 1351, 1356 (Fed. Cir. 2000). “Unless the claim is specific as to the number of elements, the article ‘a’ receives a singular interpretation only in rare circumstances when the patentee evinces a clear intent to so limit the article.” Id. Thus, the claim as amended, which removes the open ended preface “comprising” and changes the modifier of “select signals” from “a” to “one or more,” does not change the scope of the claim in that respect. It merely is a different phrasing. Thus, as we stated in the Institution Decision, any description of a system with one signal would necessarily support a claim to one or more signals. Inst. Dec. 28. Additionally, the claim, as amended, does not suggest there is choice between alternatives that would meet this claim. For example, the claim does not require a choice between a first type of signal and a second type of signal. The claim recites “one” signal, which can be optionally accompanied (“or”) by “more” signals.” slip op. at 8
